It delivers 400 W peak pulse power and is AEC-Q101 qualified for automotive electronics protection.
For engineers reviewing the P4SMA130AHE3_A/I datasheet, P4SMA130AHE3_A/I pinout, P4SMA130AHE3_A/I application, or P4SMA130AHE3_A/I equivalent, this device serves as a robust, RoHS-compliant transient suppressor for DC power rails and signal lines where fast response (<1 ns), low clamping ratio (1.38×VWM), and high surge reliability are required in harsh environments.
Technical Context
The P4SMA130AHE3_A/I operates as a unidirectional avalanche diode with glass-passivated junction, enabling sub-nanosecond response to ESD and lightning-induced transients. Its 120 °C/W junction-to-ambient thermal resistance and 150 °C maximum junction temperature support operation in thermally constrained PCB layouts.
It complies with AEC-Q101 stress testing for automotive use and meets UL 497B recognition (QVGQ2). The device features matte tin-plated leads, J-STD-002 solderability, and MSL Level 1 rating (260 °C peak reflow), making it suitable for high-volume automated SMT assembly without derating.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ130A-E3/5A | Same VWM (111 V), identical SMA package, but rated for 400 W only up to 91 V; above 91 V, PPPM drops to 300 W per datasheet. | Less suitable for sustained high-energy surges in automotive load dump where full 400 W capability is required above 91 V. | Select P4SMA130AHE3_A/I when full 400 W rating across full temperature range and AEC-Q101 qualification are mandatory. |
| 1.5SMC130A | Higher package thermal mass (SMC/DO-214AB), 120 °C/W RθJA vs. 120 °C/W (same), but larger footprint (7.11 × 6.22 mm vs. 4.50 × 3.99 mm). | Requires more PCB area; not ideal for space-constrained automotive modules or dense consumer PCBs. | Choose P4SMA130AHE3_A/I for compact layouts where SMA's smaller DO-214AC footprint saves >40% board area. |
Compared with SMAJ130A-E3/5A and 1.5SMC130A, the P4SMA130AHE3_A/I uniquely combines AEC-Q101 qualification, full 400 W rating at 130 V, and minimal SMA footprint-enabling automotive-grade surge protection without layout compromise or derating penalties.

FAQ
What is the clamping voltage of the P4SMA130AHE3_A/I at its rated peak pulse current?
The P4SMA130AHE3_A/I has a maximum clamping voltage (VC) of 179 V at 1.7 A peak pulse current under the standard 10/1000 µs waveform. This value is measured with the device mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per JEDEC guidelines, ensuring repeatable lab-to-production correlation for surge design validation.
Is the P4SMA130AHE3_A/I suitable for automotive applications?
Yes, the P4SMA130AHE3_A/I is AEC-Q101 qualified and carries the HE3 suffix denoting RoHS-compliant, halogen-free, and automotive-grade construction. It passes temperature cycling, high-temperature reverse bias (HTRB), and human-body-model ESD tests per AEC-Q101 Rev G, making it appropriate for engine control units, body electronics, and ADAS power domains.
What does the "_A/I" suffix mean in P4SMA130AHE3_A/I?
In P4SMA130AHE3_A/I, "A" denotes the revision level of the AEC-Q101 qualification, and "I" specifies the packaging format: 7500-piece 13-inch plastic tape-and-reel delivery. The "HE3" portion confirms RoHS-compliance and AEC-Q101 qualification, distinguishing it from commercial-grade E3 or M3 variants.
How does the P4SMA130AHE3_A/I compare to bidirectional TVS diodes like P4SMA130CA?
The P4SMA130AHE3_A/I is unidirectional and optimized for DC power rail protection where polarity is fixed, offering lower leakage (<1 µA) and tighter VBR tolerance than bidirectional equivalents. In contrast, P4SMA130CA supports AC or floating signal lines but exhibits higher ID and wider VBR spread-making P4SMA130AHE3_A/I preferable for 12 V/24 V automotive supply rails.
What is the thermal resistance of the P4SMA130AHE3_A/I, and how does it affect layout design?
The P4SMA130AHE3_A/I has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W when mounted on minimum recommended pad layout. To sustain repeated surges, designers must provide adequate copper area (≥5.0 mm × 5.0 mm per terminal) and avoid thermal isolation-especially critical in sealed automotive enclosures where ambient can exceed 105 °C.
